39-fyi-ac-output-location.patch

[Akim Demaille]

Index: ChangeLog
from  Akim Demaille  <address@hidden>
        * automake.in ($ac_output_location): Replace with...
        ($ac_config_files_location): this.
        (&scan_autoconf_traces): We don't need $file and $line, $here is
        enough.
        (&scan_one_autoconf_file): Use `$in_ac_output' to store the macro
        name (AC_OUTPUT or AC_CONFIG_FILES) for error messages.
